
10- 03 =【2】
Feedback (detected value) is derivative controlled in unit time set in parameter 10- 07.

10- 03 =【3】
Ddeviation (target value - detected value) is derivative controlled in unit time set in parameter
10- 07. If the deviation is positive, the output frequency decreases, vice versa.

10- 03 =【4】
Feed back (detected value) is derivative controlled in unit time set in parameter 10- 07.
If the deviation is positive, the output frequency decreases, vice versa.
Note:
For 10-03 = 1 or 2, If the deviation is positive, the output frequency increases and, vice
versa.
For 10-03 = 3 or 4, If the deviation is positive, the output frequency decreases, vice versa.

When 10-03= 【5~8】, Output frequency = PID output frequency + frequency command (10-
03 = 【1~4】) .
